TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 399,807, dated March19, 1889.

Application filed April 21. 18E 8. Serial No. 271,485. (No model.)

If 0 all whom it Hwy concern.-

.Be it known that I, \VILLIAM \VESTLAKE, of Brooklyn, county of Kings,and State of New York, have invented certain new and useful Improvementsin Tubular Lanterns, of which the following is a full, clear, and exactdescrlptlon, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

My invention relates to the well-known general class of tubular lanternsor tubular lamps, and has for its object the provision or production ofa lantern or lamp of the class named wherein the globe may be easily andquickly raised or lowered and securely held without the aid of springs,wherein the light will. be directed to best advantage, and whereinvarious advantages in the matters of construction and operation will besecured, as will be herein first fully explained, and whereof theprominent features of improvement will be pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is an elevation of a lantern completed in accordance with my inventionand involving my improvements. This may be denominated a frontelevation, and shows the globe seated on the perforated bottom plate, aswhen the lantern is in use. Fig. 2 is a view like Fig. l, but showingthe opposite side of the lantern and the globe raised to afford accessto the wick or flame. Fig. 3 is a view in side elevation, omitting thereflector and showing the globe in position to be detached, the tubesbeing broken away. Fig. i is a plan of the top of the globe, showing thesingle lug or projection thereon. Fig. 5 is a plan of the bottom of thelantern or lamp, illustrating the spread of the open base.

In all the figures like letters of reference wherever they occurindicate corresponding parts.

A is the globe or flame-protector; .l B, the side tubes which conductair down to the under side of the burner-cone; C, a central airpipecommunicating with tubes B B, and D the dome located above the globe.

The globeA rests upon a perforated bottom plate, E, which in turn restsupon the burnercone. At the upper part of the globe, and

formed therewith, is a projection, u, the purpose of which is to engagewith or ride upon or against inclined bearings attached to the dome I).These liearings are shown at l) and (1. They may be made of wire orother suitable material and in one or more pieces. At the front they areseparated, as shown in Figs. 1 and 3, by a distance sufficient to permitthe top of the globe to be canted out between them, and on the oppositeside they approach each other more or less closely. The portion 1) isinclined downwardly, proceeding from the front opening or space. Byturning the globe to the right (in the example shown) the projection arides beneath the section I) and crowds the globe firmly down to itsseat on the bottom plate, thus locking the globe in place and holdingthe burner, burner-cone, and bottom plate in working position. From thisposition, by turning the globe to the left until the projection a. isclear of the section b, it is unlocked, and may then be detached, asindicated in Fig. 3; or by further turning it to the left the projectionto is made to ride upon the section 0, which inclines upwardly, and thusthe globe is raised from off its seat, as shown in Fig. 2. This affordsaccess to the wick for lighting or to the flame for extinguishing.

As will be seen, in order toraise or lower, lock or unlock the globe, itis only necessary to revolve the same, and the construction obviates theuse of springs or other complicated locking and holding devices.

F is a reflector calculated to direct the light from the flame downtoward and beyond the base of the structure. This may be made of plainor fancy metal, and is sustained upon the inclined side tubes by shortguidepieces or extensions (Z (I. It is mounted above the position of theflame, but below the top of the globe, so that light may proceed fromabove aswell as from below the reflector. It is easily adjusted to placeor removed. It

operates as a complete guard for the globe, and when in place it alsooperates to guide the globe while being adjusted up or down. That thestructure may be used to best advantage to throw the light downwardly,(where it is most required) the globe is made small at the bottom,preferably a trifle less in diameter there than at the top, which is thereverse of former constructions. This enables me to make the bottomplate correspondingly small, and consequently to obviate the productionof so much shadow.

. The 0ilpot G, instead of being spread out horizontally, as in otherlamps, is also contracted in diameter to about that of the bot tomplate, so as not to intercept the light.

The base of the lantern or lamp is made open to permit the passage oflight. It is composed ot' two wires, 6 c, or equivalent strips, suitablybent to afford the desired spread, and secured to the sides of theoil-pot by solder or otherwise. Of course the open base might be made ofone piece; but it is preferred as shown, because of the ease with whichit may be made and applied.

The parts being assembled as in Fig. 1, the reflector directs the lightdownwardly, and, being slightly inclined, will direct it beneath theoil-pot in such a way as to illuminate the entire space below thestructure when carried in the hand. All the parts are simple and durableand the improved structure well cal culated to answer the purpose orobject of the invention, as previously set forth.

Having now fully described my invention,

what I claim as new herein, and desire to secure by Letters Patent, is

1. In a tubular lantern or lamp, the combination, with the globe havinga projection at top, of the two inclined Ways secured to the dome, thesaid ways being separated from each other at the front and arranged tooperate substantially as shown and described.

2. In a tubular lantern or lamp, the combination of an annular reflectorsurrounding the globe mounted upon the side tubes above the position ofthe flame and below the top of the globe, the oil-p0t, and an open baseapplied on said oil-pot, substantially as and for the purposesexplained.

3. In a tubular lantern or lamp, the combination of an annular reflectormounted upon the side tubes, contracted bottom plate, contracted oilpot,and open base secured to the oil-pot, substantially as and for thepurposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of two witnesses.
